Tips and Tricks to Solve Logical Reasoning Questions

by

Logical reasoning tests your ability to analyze information, recognize patterns, and draw valid conclusions. Here are some effective strategies to tackle such questions:

1. Understand the Question Type

Logical reasoning questions come in various forms, including:

  • Deductive Reasoning (Syllogisms, Logical Puzzles)
  • Inductive Reasoning (Pattern Recognition, Series Completion)
  • Analytical Reasoning (Seating Arrangement, Blood Relations)
  • Critical Reasoning (Assumptions, Strengthening/Weakening Arguments)

Identify the type before attempting to solve it.

2. Break Down the Information

  • Read the question carefully and extract key details.
  • For puzzles or seating arrangements, draw diagrams or tables.
  • Eliminate irrelevant information to focus on what matters.

3. Look for Patterns & Sequences

  • In number/letter series, check for arithmetic, geometric, or alternating patterns.
  • For visual reasoning (like mirror images or embedded figures), observe symmetry and transformations.

4. Use Elimination Method

  • In multiple-choice questions, eliminate obviously wrong options first.
  • Narrow down choices logically instead of guessing randomly.

5. Apply Logical Rules

  • For syllogisms, use Venn diagrams to visualize relationships.
  • In coding-decoding, identify consistent rules (e.g., letter shifts, symbol replacements).

6. Practice Common Question Types

  • Blood Relations: Memorize standard terms (e.g., maternal, paternal).
  • Direction Sense: Sketch movement paths step-by-step.
  • Seating Arrangement: Use symbols (○ for people, arrows for directions).

7. Avoid Assumptions

  • Stick strictly to the given information; don’t add external knowledge.
  • In “if-then” statements, confirm whether the converse is valid.

8. Manage Time Effectively

  • Skip time-consuming questions and return later.
  • Allocate more time to complex puzzles but don’t overthink.

9. Strengthen Critical Thinking

  • For argument-based questions, identify premises and conclusions.
  • Evaluate assumptions and possible flaws in reasoning.

10. Practice Regularly

  • Solve puzzles, riddles, and past exam papers.
  • Use apps/books (like LSAT, GMAT guides) for structured practice.

Bonus: Quick Checks for Common Errors

  • In Syllogisms: Ensure the conclusion follows from the premises.
  • In Series Completion: Verify if the pattern holds for all terms.
  • In Assumption Questions: The assumption must support the argument.
